Yes, I was going to suggest the attachments because the attachment mechanisms 
also cause events to be sent.

I would think so, too.

It would certainly be nicer to be able to suppress notifications in the 
attachment API, but that would involve enhancing Moin, and I don't really know 
what the situation is with regard to getting patches into upstream Moin 1.x 
these days.

An alternative might involve accessing the stored attachments and comparing a 
checksum of the content with the thing you're considering attaching.
